Bently Nevada Vibration and Acceleration Module 3500/42 (128229-01, 176449-02)
The bently nevada 3500/42M displacement/velocity acceleration monitor can accept 1 to 4 displacement, velocity or acceleration sensor signals. It is a 4-channel monitor that can accept signals from displacement, velocity, and acceleration sensors. By processing these signals, it can complete a variety of vibration and position measurements and compare the processed signals with the alarm values programmed by the user. Each channel of the 3500/42M can be programmed using the 3500 Framework Configuration Software.
